VFR conditions are expected with the exception of perhaps a couple hours of MVFR cigs right around sunrise. 11 && .PREV DISCUSSION... /ISSUED 918 PM CDT Mon Jul 16 2018/ UPDATE... No major changes were made to the forecast. Overall quiet night with some lingering haze expected. 11 PREV DISCUSSION... /ISSUED 335 PM CDT Mon Jul 16 2018/ DISCUSSION... Hot and dry conditions will prevail across Southeast Texas over the next week as expansive upper ridging builds across the state from the Four Corners region. Saharan dust will linger across the region through Tuesday, but NASA GEOS-5 modeling shows this plume dispersing beginning this evening through Tuesday with dust likely unnoticeable by Wednesday. Patchy, intermittent fog may be able to develop during the early morning hours Tuesday and Wednesday but increasing subsidence from the ridge should result in enough column drying to limit fog development by late week. As mid-level heights climb into the 594-595 decameter range mid- week, afternoon high temperatures will climb into the mid 90s to lower 100s inland and upper 80s to lower 90s along the coast by the end of the week. This is expected to produce heat index values in the 105-110 degree range with the potential for briefly higher observed values during the afternoon hours along the coast as the sea breeze moves inland each day. Huffman MARINE... The maritime forecast will remain fairly unchanged over the next several days as surface high pressure expands across the entire Gulf and kills any discernible pressure gradient. Weak southwesterly breezes will occur over more western waters and bays with more of an easterly component to the onshore flow over the more eastern waters. Weak breezes will keep average sea heights at or under 3 feet. High pressure at all levels will also inhibit any shower or thunderstorm development through the week. Less than a slight chance that more eastern Gulf waters could experience early day isolated rain activity focused along a potential land breeze boundary making it into the nearshore waters. 31 && .PRELIMINARY POINT TEMPS/POPS...
